FAQ
Q1: Is this a complete bearing set for a full engine rebuild?
A1: Yes, this product is sold as a complete set containing both the main bearings (for the engine block) and the connecting rod bearings. It is intended for a comprehensive bottom-end engine overhaul of a Caterpillar C15 engine.
Q2: How do I ensure I am ordering the correct size bearings for my engine?
A2: This set is manufactured to the OEM standard size. However, during an engine rebuild, it is critical to measure your crankshaft journal diameters with a micrometer to check for wear or previous machining (e.g., grinding for undersize bearings). Always match the bearing size to the actual measured journal size.
Q3: What is included in the quality documentation?
A3: With your shipment, you can request supporting documentation which includes a machinery test report detailing material and dimensional checks, and a video outgoing-inspection record that visually confirms the part’s condition and packaging prior to dispatch. This provides transparency and confidence in the product’s quality.
